11 Claims, (Cl. 198-25) -This invention relates to a delivery device forcigarette making machines, comprising a longithe grooves of whichcigarettes are laterally inserted.

In machines which operate at a high speed, known delivery devicesreadily lead to disturbances, and even the lateral insertion into thedrum is unable, in itself, to provide a remedy, because the frictionbetween the inserting device and the cigarettes which are being fed isexcessive. The present invention obviates this disadvantage by the factthat the inserting device, moved laterally in timed relation with therotation of the drum, possesses a component of motion in the directionof feed of the cigarettes.

The accompanying drawing shows by way of example two constructionsaccording to the invention.

Figures 1, 2 and 3 show a longitudinal section,

a plan view, and a side view respectively, of one construction, and

Figure 4 is a plan view showing a modified construction.

The cigarette rod a is carried in known manner through the cutting tubet in which the cigarettes are cut to the required length. The cigarettesthen pass through a guiding tube 0 and between two conveying beltsveying belt d ends or bands (1 and e. The conjust in front of a grooveddrum 1. The pulleys d and it over which the belt it runs may be madeconcave so that the belt is arched as shown in Figure 3. The lower belte passes over a roller 6 then beneath the cigarettes and along to thegrooved drum j, and is carried in front of this drum over two rollers eand c The drum f itself, which continuously or intermittently rotates ona shaft 9 is driven in any desired manner, not shown in the drawing. Thecigarettes that arrive beside the drum f are moved into the grooves h,of the drum, in the case of the construction according to Figures 1 to3, by means of two cams i and i which rotate in the same direction andwith the same speed. As shown in Figures 2 and 3 there is suflicientspace between the peripheries of these cams and the drum f for thecigarettes. When the cams rotate, they push the cigarette lying besidethem, away from the belt as shown more particularly in Figure 3 e andinto the groove of the A protecting metal sheet is prevents thecigarette from falling out of the drum. The drum has an annular groove mwhich extends to of the grooves h an ping finger n. This the bottoms din which engages a stripfinger presses the cigarettes out of the groovesh so that they fall on to a conveying belt 0, which then conveys themforward in the ordinary way. The conveying belt 0 passes over a roller 0and is driven in a manner not shown in the drawing. 1

The cigarettes will assume different positions in their longitudinaldirection on the drum f. In order to align them so that they can bedelivered in the correct position to the band 0, a dressing device isprovided in the form of a swash plate 10 or inclined disc p. The hub pof the said disc is fast on a hollow stub shaft q which is journalled ona pin q The latter is fast on a pin T which, for example, is rigidlymounted in the bearing r that is to say, it is not rotatable in themachine frame. The pin q is connected by means of a universal joint s toa shaft s which engages in the shaft g and is connected therewith forrotation in common. 0n the disc p are provided arms 11 which'engage'slots f in the drum f. The disc p consequently rotates about the pin 11when, on the rotation of the drum 1, it is driven due to coupling bymeans of the universal Joint with the driving shaft q of said joint. Atthe same time, the arms p make a reciprocating movement in the slots 1and on entering the slots, as will be seen in the case of the lowermostcigarette, they push the latter into the correct position within thegroove in which it can be delivered to the conveyor band 0. I

Figure 4 shows a second constructional form of the invention. In thiscase, instead of the rotating cams i and i there is provided a parallelcrank device comprising a pusher t carrying at its front end a facingmember t which engages the cigarettes, the pusher t being connected tothe two crank-pins c and v The crank-pins are driven by two shafts w andw in a manner not shown in the drawing. In operation the pusher t will,during its movement towards the drum and in the direction of thecigarettes, engage the clgarette, press it into the drum, andsimultaneously make with it a short movement in the direction of thecigarette, the member t braking the movement of the cigarette. The plate1! then moves from the cigarette and returns into its initial position.

For the same reason as that for which the facingmember t is provided,the cams i and i (Figures 1 to 3) may also be provided with a brakingfacing i The conveying belts d and e are advantageously caused in aknown manner to move with a velocity somewhat greater than that of thecigarette rod in order that the cigarettes may be spaced apart duringtheir conveyance on these belts, and that consequently there may be aninterval sufiicient to prevent on the insertion of the foremostcigarette, the succeeding one from being injured or carried alongtherewith. As a pushing-in device there might also be employed a belt orband provided with fingers and constantly running around the drum.

I claim:-

1. A delivery device for cigarette rod machines comprising, incombination. a rotating drum provided with grooves adapted to receivethe 01g.- arettes, means for delivering said cigarettes ardrum andadapted to deliver the cigarettes by the side of the drum and rotatablecams arranged laterally of the drum into said grooves.

2. A delivery device for cigarette rod machines comprising, incombination, a rotating drum produce the feedirig 3. Delivery mechanismfor cigarette making the grooves through the line of feed of thecigarettes as the drum rotates.

- 4. A device according to claim 3, in which two conveying belts areprovided which engage the cigarettes between them at the outlet of themachine. one of the belts passing beneath the inserting device andextending across the length of the drum.

5. A device according to claim 3, in which the inserting devicecomprises rotatable cams.

6. A device according to claim 3, in which the inserting devicecomprises a pusher, and a crank driving device for actuating the pusher.

7. A device according to claim 3, in which the inserting devicecomprises rotatable cams and a braking facing which reduces the feedingvelocity of the cigarettes.

8. A device according to claim 3, in which the inserting devicecomprises a pusher, a crank: driving device for actuating the pusher,and a braking facing which reduces the feeding velocity of thecigarettes.

9. A device according to claim 3, in which the d um has a greater lengththan the cigarette, and in which an inclined disc is provided whichrotates about an axis inclined to the axis of the drum for aligning thecigarettes on the drum.

10. A device according to claim 3,. in which the said disc beingprovided with arms which project into the grooves through slots in thedrum.

' 11. A device according to claim 3, in which the drum has a greaterlength than the cigarette, and in which an inclined disc is providedwhich rotates about an axis inclined to the axis of the drum foraligning the cigarettes on the drum, said disc being driven by beingcoupled to the shaft of the drum by means of a universal joint.
